Device A Address Counter Register (ADCAn)
A double-word, read/write register. Holds the current address of either the source data item or the destination location, ac-
cording to DIR bit in DMACNTLn register. ADCAn is updated after each transfer cycle by INCAn, INCBn, ADA and ADB in
DMACNTLn register.
Location: Channel 0 - 00 FA00
Type:
Device A Address Register (ADRAn)
A double-word, read/write register. Holds the starting address of either the next source data block, or the next destination data
area, according to DIR bit in DMACNTLn register.
Location: Channel 0 - 00 FA04
Type:
Device B Address Counter Register (ADCBn)
A double-word, read/write register. Holds the current address of either the source data item, or the destination location, ac-
cording to DIR bit in DMACNTLn register. ADCBn is updated after each transfer cycle by INCAn, INCBn, ADA and ADB in
DMACNTLn register. In Direct (Fly-By) mode, this register is not used.
Location: Channel 0 - 00 FA08
Type:
Device B Address Register (ADRBn)
A double-word, read/write register. Holds the starting address of either the next source data block or the next destination
data area, according to DIR bit in DMACNTLn register. In Direct (Fly-By) mode, this register is not used.
